  • Patent number: 8893709
    Abstract: The present invention provides a kitchen ventilation hood for ventilating the area above a cooking area and for exhausting air containing cooking by-products from a cooking station to an external environment through an exhaust duct while using a reduced airflow. The kitchen ventilation hood of the present invention is designed to minimize the required airflow through the hood in order to thoroughly evacuate the cooking by-products. The kitchen ventilation hood of the current invention has a structure incorporating an arched interior hood surface that directs the air to be ventilated through the air intake gap and the grease filter. The more efficient airflow resulting from the arched interior hood surface allows for removal of cooking by-products with a lower airflow than that required by currently available ventilation hoods. As such, the kitchen ventilation hood of the present invention represents a significant improvement over prior ventilation hoods.

  • Patent number: 5107097
    Abstract: A forced air convection oven having an open front and a door for closing the open front, a centrifugal air circulating blower on a horizontal axis located generally centrally on the rear wall of the cavity with heaters adjacent the rear wall for heating the air circulated by the blower. An air distributor cage unit is mounted for removal as a unit through the front opening in the housing and the top, bottom and opposing side panels of the cage have a multiplicity of air discharge openings therein for passing air into the cage for flow therethrough to the return outlet in the rear wall. A food tray support rack is mounted for rotation about a vertical axis in the cage and is removable through the opening in the front of the cage for cleaning.

  • Patent number: 5042689
    Abstract: The vent on demand system for bottled water coolers employs a suction wand having water suction tube, vent tube and air pressure tube for sensing the water level within the bottle. The plumbing system is only exposed to atmospheric air during water dispensing. Air pressure trapped within a bulb well located at the lowermost end of the wand responds to water level within the bottle by changing air pressure which is sensed by a pressure switch employed to disengage the pump when water levels approach empty. A check valve prevents air from entering the water suction tube during bottle replacement and the vent tube is coupled through a vent valve which maintains the water delivery system in a sealed state, only venting to atmosphere during actual water delivery. The vent valve is simultaneously actuated when either hot or cold water buttons are depressed with the pump being actuated momentarily thereafter.

  • Patent number: 4903935
    Abstract: The improved valve construction provides low force actuation and is therefore suitable in applications where children and handicapped persons may need to operate the valves. The pinch-type valve employs a lever arm pilot which supports a section of tubing in the fluid dispensing circuit. The lever arm is snap fit onto a valve plate and is adapted for rocking movement about a pivot point at one end of the lever arm. A valve cage supports a compression spring which applies a force upon the lever arm tending to depress the lever arm and its associated tube pinching valve seat into pinching contact with the tube. A force applied to the lever arm opposite the pivot point relieves the pinching force and the tube is thus opened for dispensing. An alternate flapper-type valve employs a valve pad encapsulated on the end of a lever arm which is in turn encapsulated in an O-ring seal so that the valve pad is situated at the center of the O-ring and the lever arm is disposed along a radial of the O-ring.

  • Patent number: 4881380
    Abstract: The plumbing module is a self-contained fully operational unit which provides the capabililty of supplying both hot or room temperature and refrigerated water or other beverages. The module may be adapted without significant modification to a wide range of products and uses, including bottled water coolers, drinking fountains and beverage dispensers. A dual parallel condenser coil in the refrigeration system takes approximately one-half the space of conventional coils and provides adequate heat dissipation without requiring forced air cooling fans.

  • Patent number: 4783002
    Abstract: The barrier free drinking fountain has an oval-shaped basin which rests on an extended cantilevered arm. The basin is an assembly of an upper bowl and a lower bowl which are assembled on the waste removal pipe and which may be readily disassembled without breaking adhesive seals. The push actuator is semicylindrically-shaped to provide a manually accessible surface spanning approximately 180.degree.. The push actuator moves both translationally and rotationally, depending on where the actuator is pushed. Translational and rotational movement of the actuator causes the water dispensing valve to operate.
